There are two layers of data at work here. The first is obvious: Central nodes represent distinct branches of tech development, from software to AI to internet to "UBICOMP" -- that is, ubiquitous computing. From those nodes, the various technologies in development sprout.

But the second layer of data is where the real futurism lies. The various nodes and technologies are arranged so that ones further off lie on toward the outside of the chart; ones that already exist or almost exist lie closer to the center.
